Xu Jiaojiao needs Si Yuchen to realize one thing, that now is not the time to speak openly with Gu Xijue.
Gu Xijue doesn't have the perspective of the Gu family, so he cannot understand how Si Yuchen ended up with Gu Xiaonuan. Besides, to that person, all the harm Gu Xiaonuan is suffering now is caused by Si Yuchen.
Si Yuchen can deny it, but he cannot completely deny it.
Si Yuchen and Gu Xiaonuan's accident definitely had a connection, Xu Jiaojiao could tell just from his eyes.
The reason why Xu Jiaojiao avoids talking about this matter is because she simply believes that Si Yuchen cannot possibly shirk his responsibility.
Now that Si Yuchen has seen Gu Xiaonuan lying in the hospital, he must take responsibility.
The relationship between Gu Xiaonuan and Si Yuchen is not so simple anymore that it can be easily clarified, so unavoidably, Xu Jiaojiao can only watch Si Yuchen solve his own personal matters.
